RADIATOR.

Application filed February 28, 1927. Serial No. 171,705.

My invention relates to radiators and in particular to drawn nonferrou s radlators It is the object of my invention to provide a non-ferrous radiator with high radiating capacity in which there will be main passageways in one direction for the heating or cool ing medium and confinedair passageways arranged in conjunction wlth the cooling or heating medium passageways arranged in a diverse or transverse direction It is my object to provide a close fitting between the two types of passageways to facilitate the radiation between the parts, the

air and the heating or cooling medium being employed. a

It is desirable but not essential to have such parts as nearly as possible made of homogeneous material without seams.

Referring to the drawings:

Figure 1 is a plan view of a radiator embodying these features;

Figure 2 is a plan view of a blank utilized for forming a perforated end member for the radiator;

Figure 3 is a section on the line 33 of Figure 1 showing the arrangement of the transverse tubular passageways with respect to the heating or cooling medium passageways;

Figure 1 is a section through a tubular member 4 Figure 5 is a section through the tubular member formed into a lozenge shape in section; 4

Figure 6 is a section through the tubular member as it is formed in its final form;

Figure 7 illustrates in section, such tubular air passageway members arranged on a heating pipe without flanges;

Figure 8 is a similar section with flanges;

Figure '9 is a section showing a twopart construction which when assembled forms both the air passageway and the heating and cooling passageway from the two parts.

I Referring to the drawings in detail, 1 refers to a heating or cooling medium pipe, any

number of which may be employed. I have.

shown a pair of such pipes in the radiator for the purpose of illustration, connected together at one end by the transverse member 2, a

header.

Threaded on each of these pipes are a series of parallel, transversely-arranged air conveying pipes of special configuration.

For the purpose of forming such pipes, I first select an ordinary drawn tubing 23 preferably of non-ferrous material which is Y formed into. a lozenge-shaped pipe shown in sageways 9 for the guidance of air over the pipes 1.

If desired, the openings 4 may have sleeves formed from the side walls 3, said sleeve being designated 10 forming broader bearing and contact surfaces on the pipes 1 for facilitatmg and improving the radiation and im proving the rigidity of the structure.

In the event it is desired to make the transverse heating pipes and the air conveying passageways out of continuous pieces of stock, I select fiat stock and form in such stock centrally thereof tapered thimbles 11 at right angles to the central flat portions 12, such thimhles 11 being opened at both ends. The flat portions 12 are bent up as at 13 at an angle to the flat portion 12 and the free ends of the sheet are bent outwardly at an angle to form the member 14 on either side of the sheet.

This member 14 overlaps a flange 15 formed on the end of a similar angular sheet margin consisting of the portions 16 and 17 bent in the reverse direction to the portions 13 and 14:. A central portion 18 is provided which has its thimble 19 adapted to receive the thim-ble 11 interiorly thereof a portion of the thimbles length.

Thus, by forming a series of successive fiat sheets, I am enabled to provide a passageway for the heating or cooling medium through the pipe formed by the thimbles 11 and 19 and a transverse air passageway, such as 20,

' through the sheets joined together along the flanges 15 and a third transverse air passageway, designated 21, between the exterior of such sheets and the exterior of the thimble 19.-

It will be understood that the headers can be made of any desired material either drawn tubings or castings and of any shape desired.

The header 2 is used simply to make a circuit for the steam dripping. The radiator can be placed in any position. The interlocking structure shown provides for reat rigidity with corresponding light welg t.

The secondary tubes with the diamondshaped endsform air chimneys for the induction of the heated air, while, at the same time, the exterior of the radiator provides a maximum of radiation surface both internally and externally and a neat, attractive appearance, permitting the radiator to be used in installations which have heretofore been impossible because of theappearance of other types of radiation.

The plate shown in Figure 2 and generally designated 22 is so formed as to fit over the endsof the diamond-shaped tubes, if desired, to present a neat appearance.

It will be observed that the sleeves 10 fit closely upon the tubing 1. I find that it is desirable in some instances to form these flanges on the tubing 1 into a close joint by drawing a tool through the tubing 1 and expanding it against the plates 3 so as to form the collars 10 providing thefiange construction shown. Such connections may be brazed if desired. The expanding action of the tool on the tube forces the walls of the tube outwardly against the edges of the plates 3, strung on the tube so that this outward pressure causes a bending of the margins of the plates 3, where they engage the walls of the tube 1, thus forming the flanges 10, or if the flanges are already partially formed, increasing the size of the flanges and improving the cross engagement of a wall of the tube 1 with the flanges 10.

It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt it to varying conditions and uses. Having thus fully described my invention,

what I claim as new anddesire to secure by Letters Patent, is:

1. In a radiator, tubular members arranged in one direction for conveying heat, and independent tubular members mounted thereon arranged in a diverse direction designed to carry air over said heating members, each of said last mentioned members forming complete integral cross tubes for conveying air in an area restricted to a cross area traversing a plurality of heating pipes, each of said independenttubular memb rs providing independent air zones for the l efinite guiding of the air over the plurality of pipes.

2. In a radiator, a plurality of spaced parallel heat conveying members, and a plurality of transversely arranged air conveying tubular members threaded thereon, said air conveying members having spaced parallel sides and enlarged heads, said enlarged heads *being adapted to form air passageways over said heating members both Within and without said transverse air conveying members.

3. A new article of manufacture for use as a radiator consisting of air conveying tubular members having spaced interiorly disposed parallel side members and expanded marginal portions and transverse heating pipes sealed therefrom and threaded therethrough.

4. A new article of'manufacture for use as a radiator tubing consisting of a tubular member having spaced interiorly disposed parallel side members and expanded marginal portions, said interiorly disposed portions having passageways for a pipe transversely thereon.

5. A new article of manufacture for use as a radiator consisting of air tubes having relatively closely arranged, spaced parallel sides and ends substantially diamond-shaped in section and cross tubes for heat passing therethrough over which the air in the air tubes passes.

In testimony whereof, I afiix my signature.
